The circuit is a Single phase motor(120V runs 4.7amps running amps), and a relay to trigger the motor on/off.
I'm looking to use a snubber circuit to protect the relay contacts for prolonged use. The motor shouldn't be switching on/off very often but to be safe.
According to this page: http://www.farnell.com/datasheets/303558.pdf
It says .5 to 1 ohm per volt so 120 v = 120ohms For amps it says about 1uf per amp. The motor runs 4.7 after startup.
For running current I would be looking for a 120ohm resistor and a 5uf capacitor.
Should the snubber circuit be valued for the running current? I also have a varistor rated for 120V, would this be a equal alternative? The varistor is rated for 1 watt of current.
